TRANSFERRER FOE V EFTREPLENISHING LOOMS.

Application filed November The invention is designed for employment in looms of the class in .which weft replenishment is effected through automatic insertion of a reserve bobbin or other weftcarrier or filling-carrier, loaded with weft or filling, into the working shuttle of a loom, with simultaneous ejection of the spent or failed carrier previously occupying the shuttle.

The invention has relation to the so-called transferrers, sometimes termed hammers, by which a fresh or reserve weft or filling-carrier is driven into a working shuttle, with resulting ejection of the spent or failed carrier. In practice, a transferrer or hammer is constructed with a head-portion which in operation strikes downward upon the top of the head of the carrier that is about to be placed in the shuttle, and in some cases it is provided with a striker-block that is disposed at a short distance transversely from the said head-portion and arranged to act against the periphery of the wound mass of weft or filling upon the carrier to ensure that the whole length of the carrier, including its tip-portion, shall become entered fully into the shuttle.

The invention provides in novel manner for mounting a. striker-block in connection with the arm of a transferrer or hammer, with facility for adjustment of the said striker-block laterally, so that it may be arranged to strike against the wound mass of weft or filling at the required place in the length thereof, and also with capacity for angular adjustment.

Illustrative embodiments of the principles of the invention are shown in the drawings. In the latter,"

F 1 shows in side elevation a transferrer or hammer having an embodiment of the invention applied thereto.

Fig. 2 is an elevation of the rear end of said transferrer or hammer, looking from the right-hand side in Fig. 1, a bobbin loaded with weft or filling,and a portion of a shuttle, being shown also.

Figs. 2 and 3 illustrate the head 1 and striker-block 2 of a transferrer or hammer in the relations with respect to a bobbin 3 11, 1925. Serial No. 58,323.

loaded with weft or filling 4 which they as sume in the operation of driving such bobbin. into the working shuttle 5 of a weft replenishing loom. As indicated in Fig. 1, the said head and striker-block are at the rear end of the transferrer-arm 6, the said arm extending rearward from the sleeve or hub 7 by means of which the transferrer or hammer is mounted upon a supporting-stud in a loom. The head 1 is furnished with a pin 8 projecting transversely outward therefrom, and striker-block 2 is mounted upon the said pin, the striker-block having a transverse hole 21 which is occupied by the said pin 8.

In accordance with the invention the hole 21 is intersected by a slit 22 in the material of the striker-block, and with those portions of the striker-block between which the slit intervenes, namely the side-portions or cheeks at opposite sides of the slit, I combine insane for approaching the said sideportions or cheeks closer together in order to contract the striker-block upon pin 8 so as to fit the latter tightly, and thereby hold the striker-block in the position upon the said pin which has been given to the strikerbloclr. In Figs. 1, 2, 3 the said means is constituted by a through-bolt 9 passing through holes in the said portions, or cheeks, with an enlarged head 91 at the exterior of one side-portion or cheek, and with a nut 92 applied to the threaded stem of the said bolt at the exterior of the other sideportion or cheek.

In Figs. 1, 2, 3, the slit 22 extends from the hole 21 to the top of the striker-block. In the modification shown in Fig. 1 the slit 221 extends downward diagonally from the hole 21 to one side of the striker-block, and the contracting means is constituted by a screw 93 extending freely through a hole in the cheek 23 which is above the slit 221, with its head 931 against the outer side of said check, and its threaded stem screwed into a screw threaded hole in the portion of the strikerbloclr which is below the slit.

As will be apparent, loosening of the contracting means will render the strikerbloclr free to be slid along the pin 8, either toward or from the head 1, and also free to be rotated around the said pin, after which through tightening of the contracting means the striker-block may be held fast in the position that has been given to it.

The described construction provides for mounting the striker-block upon the pin 8 of the transiferrer or hammer, and for lateral and angular adjustment thereof, without requiring any holes, notches, or the like to be made in the said pin, and Without any roughening or scoring of the pin as the re sult of tastening the striker-block in place thereon.

hat is claimed as the invention is 1. The combination comprising a transferrer or hammer of a Weft-replenishing loom, a pin extending outward therefrom, a striker-block having a transverse hole therethrough which is occupied by the said pin, and split as described, and means for contractmg the Wall of said hole upon the pin to ciamp the striker-block in adjusted posi- 20 tion upon the pin.

The combination comprising a trans terrer or hammer of a Weft-replenishing loom, a pin extending outward therefrom, a striker-block having a transverse hole therethrough WlliCll is occupied by the said pin, and split as described, and a screw-threaded member by which the portions at opposite sides of the slit may be drawn together to clamp the striker-block in adjusted position upon the pin.
